I cannot say that I am very up on your sich but I can tell you that acting like nothing is wrong after a blowout is common in many relationships. For some people it is due to embarrassment over the event, for some it is avoidance of the real problem or problems. There was some stupid behavior there, no question however, it does appear that your H has some issues with you hanging out with other friends. Given that, it surprises me that he so easily suggested that you take someone else to something you were going to do together. Is he usually so up and down about the topic?
